Description of the Invention (1) Field of Invention The present invention relates to a device for cutting or trimming the hair and hair of humans and animals. This new device provides a disposable blade head with blades, which simplifies the maintenance of very sharp mechanical tools in a very economical way. First, w. 刖 Technical descriptionS There are many types of devices used to cut or trim or cut hair before S. Including these devices, most of them are called hair clippers. 0 The hair clippers that were originally designed and developed include Blade 5 It can be removed from the head of the hair clipper and sharpened to maintain the cutting performance of the hair clipper device. This blade can be fixed to the head of the hair clipper with screws or the like, or can be clipped or Other restraints I and I g are attached to the hair clipper. More modern hair clippers include a head that is designed to include replaceable blades. This blade is not intended to be continuously sharpened> but can be removed or discarded. Announcement, January 8, 1955 US Patent No. 2, 722, 742 is for this kind of equipment: price: an example of 0; and 5 disposable hair clipper head combinations have been designed to be used with hair clippers ^^ Disposable plastic hair cutting device: device! An example of a head combination is disclosed on January 14, 1.986 • U.S. Patent No. 4,563 5 81 4 No. 10 The present invention provides an improved structure The head combination of a hair clipper with a disposable blade. The whole combination is that the head with the blade is disposable but uses a metal blade. If necessary, only the blade can be discarded 5 and the head can be reused. However, the structure 3- is not designed to be durable. 499350 2. Description of the invention (2) Consumption and use. The head and blade are structured to minimize problems encountered with existing removable / disposable heads and blades, such as thermal constraints on the head and blades, and problems that can bite and pull hair. The supporting front edge of the base element of the present invention does not have a structure such as a comb tooth under any part of the blade. Such comb teeth will bite and pull the hair, such as US Patent No. 4,328, published on May 11, 1982. As shown in 616, it has comb teeth under the blade teeth. When the two tooth elements are not in contact, the hair will be bitten and pulled. In addition, the two blades of this invention are slightly concave along the longitudinal dimension of the entire blade relative to each other. This reversible blade can be bitten and pulled due to curling and separation, and other problems. U.S. Patent No. 4,765,060, published on August 23, 988, discloses that there is a curved portion at the tip of the blade, which can cause separation problems due to the lack of a continuous concave shape along the longitudinal axis. The blade of this invention has many serrations on the teeth to reduce heat build-up and provide structural strength to the teeth. This need not be accomplished by providing cuts in the tooth edges, as is the case with shearing blades, to provide softness. Because this incision can cause loss of lubricating oil and the disadvantage of biting and pulling hair. Generally, the new structure provides better cutting efficiency and reduces heat transfer to the object to be cut. This disposable system improves cutting efficiency performance and can be configured for use with combs on existing devices. SUMMARY OF THE INVENTION An object of the present invention is to provide a disposable hair clipper blade head combination, which has an improved hair clipper blade head structure, which can reduce 499350. 5. Description of the invention (3) Friction and improved blade Heat dissipation of head and blade combination. Another object of the present invention is to reduce the warpage of the head and / or the blade when the hair is used, so as to reduce the hair being pulled by the bite between the blades instead of being cut smoothly. Another object of the present invention is to provide a disposable blade head and blade design that can be used with existing comb clips. Another object is to provide a blade head for use with a spring-locked comb. Still another object of the present invention is to provide an upper blade track structure, which can reduce the friction loss of the hair clip driving ear. The driving ear, which is generally made of plastic material, is engaged with the upper blade when the hair clipper is driven back and forth . Another object of the present invention is to provide a shield for an empty room of a hair clipper for accommodating a blade head to reduce the amount of hair entering during a cutting operation. Still another object of the present invention is to include protrusions at a base member thereof to accommodate a plurality of hair clipper blade holder mounting devices of different sizes. Other objects of the present invention will be apparent from the following drawings and description.

Detailed description of the preferred embodiment of the present invention The disposable blade head is basically a combination of four pieces fixed together, that is, the base, the lower and upper blades, and the spring. The base serves as a support for the entire assembly and contains an accessory element that can be clipped to the hair clipper. A spring holds the elements together, forces the blades together, and contains a runner under which the upper blade slides. Combs can also be included. Another embodiment uses a screw fastener to lock the spring, and uses a spring lock to fix the comb. Also included is a plastic comb for use with spring locks. A 499350 V. Description of the invention (6) The deflection plate can also be added to the spring structure to prevent hair from entering the hair clipper empty room. Referring to FIGS. 1 to 15, the disposable blade head (1) has a base portion (2), which has a rear mounting portion (3) and a lower blade support portion (4). The rear mounting part (3) has an upright central bridge (5) and its hair clipper (6) fixing ears (7). The lower blade support (4) has a post (8) for fastening the lower blade (9). The supporting front edge (37) of the lower blade supporting portion (4) does not extend and protrudes from the lower teeth (1 3) of the lower blade (9). This can alleviate the problem of the existing blade head, that is, the blade supporting element tends to bite and pull the hair on the supporting base when cutting. The lower blade (9) is installed in the lower blade support portion (4), and the perforation (14) thereof can receive the pillar (8). The post (8) prevents the lower blade (9) from moving horizontally relative to the lower blade support (4), while still allowing the lower blade (9) to move vertically. This provides a vertical "floating" condition that maintains contact with the upper blade (1 5) even when the blade is curled or warped, for example, due to heating. The posts (8) and perforations (1 4) can also make the blade easy to replace, and will not flatten the curvature of the recess of the blade, because it is permanently fixed in the appropriate position on the head of other blades . The lower blade (9) has a generally flat rectangular shape, and its recess (10) extends over the longitudinal length of the blade. Ribs (1 1) are formed in the recesses (1 0) to provide structural strength and help reduce heat buildup. The lower blade (9) also has serrations (1 2) or wrinkles formed on the lower teeth (1 3) to reduce sliding friction surfaces, reduce heat accumulation, allow coolant to flow through, and provide structural strength. The lower blade (9) is installed in the lower blade support portion (4), and the perforation (14) can accommodate 499350. V. Description of the invention (7) Post (8). The upper blade (1 5) is arranged in a sliding relationship with the lower blade (9), and its lower teeth (1 3) are parallel to the upper teeth (1 6). In operation, the upper blade (1 5) slides longitudinally relative to the fixed lower blade (9). The upper blade (15) is generally a flat rectangular shape, and its recess (17) extends over the longitudinal length of the blade. As shown in Fig. 2, it can be formed in the shape of a side arched upward during the punching operation. A plurality of upper teeth (1 6) are formed at the front part, which have similarities to the lower teeth (1 3). There is a groove (18) parallel to the front tooth margin and spaced from it. The trailing edge (19) of the upper blade (1 5) contains an enlarged recess (20), which is used to receive a driving ear (2 1), or other driving elements of the hair clipper (6). A pair of track portions (22) are formed in the enlarged recess (20) to reduce the reciprocating operation of the hair clip driving ear (2 1) to cause the upper blade (1 5) to slide over the lower blade (9) for reciprocating sliding abrasion. The track part (22) preferably has a rounded edge (38) to reduce the wear of the driving ear (2 1). However, it is also possible to use a lug (4 0) with a suitable curve as shown in Figure 5 (A). ◦ Spring (2 3)-generally U-shaped element made of spring steel, etc., which has an opposing arm. (24), the shape of which can be fitted to the back edge (25) of the base member (2) seat portion (3). The opposing arm (24) can also be restrained on the base element (2) by the connection of the perforation (26) of the arm and the fixed post (27). The opposing arm (24) is bent upward from the base element (2), and protrudes forward above the upper blade (15) in an arched manner, and terminates in a downward manner to form a laterally narrow opener (28) And connected with the groove (18) of the upper blade (15). The opener (28) is preferably provided with a surface such as a plastic coating 'sleeve to make it easy to slide in the groove (18). 499350 V. Description of the invention (8) The spring member (23) can also be fixed to the base member (2) by the screw fixing method. As shown in Figure 3, the fixed post (27) is replaced by a perforation (47), and the perforation (26) of the arm is a threaded hole (46) for receiving the bolt (48). In addition, the perforation (45) allows the bolt to pass through the upper part of the opposing arm (24). The screwing of the bolt (48) to the spring member (23) provides a method to allow the spring member to be removably fixed and adjust its tightness. Therefore, when used to cut fine or fluffy hair, the tension can be relaxed to reduce the blade's wear due to friction and heat; and the tension increases when thick and tangled hair is cut. The spring member (23) may also have an extended plate or a deflection plate (55), as shown clearly in Figures 3A and 12 to prevent the hair from entering the hair clipper empty room (41) during the cutting operation. )in. In a preferred embodiment, the lower blade (9) and the upper blade (1 5) are formed in a slightly concave shape along their longitudinal dimensions, which face each other and are parallel to the rows of blade teeth (13, 16). In the plane, as shown in Figures 4 and 8. This can be used to counteract the warping and partial separation of blades from the ends (29, 30) caused by thermal build-up due to sliding friction during use. This warping occurs during manufacturing and use. The upper blade (1 5) can also be modified to have a rectangular opening rivet to be used as a hot perforation (70) to further promote heat dissipation. The blades (9, 15) can be formed by punching, cutting and / or punching in manufacturing. When manufacturing, rough blades are present in the blade side of the cutting tool. In the preferred embodiment, the rough coupling blade is at the top edge, i.e. the edge of the blade between the blades. Therefore, ‘the blade only needs to be processed on the coupling edge’, and you can participate. -10- 499350 V. Description of the invention (9) The tooth-shaped edge still helps to cut hair without touching the skin of the object and causing injury. A fixing hole (44) may be provided to assist in fixing the upper blade (5) to the fixture. Referring to FIG. 13, a large-tooth comb (3 1) is fixed to the disposable blade head (丨). The miniaturization and back-to-front or lateral dimensions of this combination are closer to the standard hair clipper head and blades' to fix the standard hair comb. When a very flat comb attachment is required, metal or other materials with a stronger structure compared with typical plastic combs (31) can also be used. Figure 14 shows an example of a thin comb (3 2) and its comb teeth (33) with grooves (34). The grooves are used to receive the leading edge (3 6) of the disposable blade head (1). ) And the trailing edge of the spring (3 5) for connecting and fixing the thin comb (3 2). The plastic comb (3 1) or the thin comb (3 2) may include one or more hooks (7 6). When a comb (3 1, 3 2) is fixed, the base element (2) is supported. The rim (37) can be fitted under the hook (76). The slot (75) can be formed on the supporting front edge (37) to engage with the hook (76). The comb teeth (3 3) may contain a ridge element (7 8) fixed to the leading edge of the tooth (7 7). This can reduce the flatness of the comb teeth (3 3) at the leading edge during the molding process. The ridge element (7 8) can help guide the hair to be cut between the comb teeth (3 3). The tooth comb (3 1), the comb piece (3 2), and the comb tooth (3 3) may be coated with a layer of low-friction substance ', for example, trade name Teflon, vacuum-deposited aluminum and clear lacquer coating, etc. And sealing materials. The tooth comb (3 1), the comb piece (3 2), and the comb tooth (3 3) can also be made of metal and silicon additives in plastic. When compared with plastic combs, for example, the strength of the material can be increased. Variations of this spring force attachment are shown in Figures 15 to 18. In this case -11-499350 V. Description of the invention (10), the back plate (5 1) replaces the snap spring (3 5), and a side element (6 5) is added. When a thin comb made of plastic or the like is required, this can provide a structure for the comb (32). If clearance is required when the comb (32) is installed, a ragged serration (6 6) can be provided. There is a slot (5 2) in the back plate (5 1), into which the extension (56) of the plate (5 3) can protrude. The plate (53) has a spring card (43), which can be connected with a spring (50) installed in the spring cavity (49). The back plate (5 1) can be wedge-shaped at the portion (68) above the slit (52), so that the extension (56) can be easily inserted into the slit (52). The plate (53) is fixed to the base element (2) by rivets (61), bolts, etc. through perforations (60) and sliding perforations (62). The pressure on the push plate (42) will compress the spring (50) because the plate (53) is pressed against the force of the spring (50). This movable extension (56) causes the comb (32) to be removed from the blade head (1) or mounted to the blade head (1). When so installed, the groove (34) will engage the leading edge (36) of the blade teeth, and when the plate (53) is relaxed, the extension (5 6) will engage the slot (5 2). The tool (6 3) and its post (6 4) can be provided as shown in Figure 16 and Figure 19 to assist in pushing in the pusher (4 2). The tool (63) and its post (64) can also have flat portions or hexagonal heads to adjust the tension of the bolts (48). Another structure of the tool (63) is shown in Figure 19A, where the pillar (64) has a rounded tip and the flat or hexagonal head (67) is located opposite to the pillar (64) Office. The base element (2) may also have more exaggerated rounded corners (54), which are used to assist the user in turning the hair clipper when the hair is in a limited area such as an animal's limb, arm, joint, etc. -12- 499350 V. Description of the invention (11) The base element (2) may also include a protrusion (58) inside the fixing ear (7), and the protrusion (58) in the socket chamber (57) is compressible . Many hair clippers (6) do not necessarily have the same tongue size. The protrusions (58) accommodate the size of many tongues to reduce vibrations caused by loose fit. When the blade head (1) is fixed to the hair clipper (6), the protrusion (58) on the fixing ear (7) serves the same purpose. The base element (2) and the lower blade (9) can be replaced by a single base blade (80). In this embodiment, the upright central bridge (5) and other components are fixed and supported by the base blade (80). The spring clip (23) is fixed to the base blade (80), and the plate (53) and its spring and other components are replaced by a leaf spring (81), which has a spring extension (82) and a slot (52).
